The spark plugs of the CS75 should be replaced every 12 months or when the mileage reaches 20,000 kilometers. The purpose of the spark plugs is to ignite the engine. During use, the electrodes of the spark plugs consume electricity through spark discharge from areas prone to discharge. Taking the 2021 CS75 as an example, it belongs to the compact SUV category, with body dimensions of: length 4650mm, width 1850mm, height 1715mm, wheelbase of 2700mm, and a fuel tank capacity of 58 liters. The 2021 CS75 is equipped with a 1.5T turbocharged engine, delivering a maximum horsepower of 178PS, maximum power of 131kW, maximum torque of 265Nm, and is paired with a 6-speed manual transmission.

















I've been driving the CS75 for several years, and spark plug replacement should follow the manual. The manufacturer recommends checking the spark plug condition every 60,000 kilometers. If you're using standard copper-core spark plugs, they may need to be replaced every 60,000 to 80,000 kilometers due to their tendency to wear out quickly. However, if you opt for higher-grade platinum or iridium spark plugs, they can last between 80,000 to 100,000 kilometers. Don’t overlook the aging issue of spark plugs—they gradually accumulate carbon deposits, leading to reduced engine ignition efficiency, sluggish acceleration, increased fuel consumption, and even potential misfiring issues. During my regular maintenance checks, I always ask the technician to inspect them as a preventive measure. Developing good habits like this can extend the engine's lifespan and save on major repair costs. Staying attentive to these details ensures your car won’t break down unexpectedly.

As a car owner, I prioritize fuel economy, and spark plug replacement directly impacts fuel consumption. My CS75 manual recommends inspection every 60,000 km, but in practice, it should be adjusted based on driving habits and road conditions. If you do more short-distance city driving with heavy dust, spark plugs are prone to carbon buildup, so I suggest replacing them earlier at 70,000 km. If you do more highway driving, you can delay replacement until after 80,000 km. Choosing the right type of spark plug also saves money: copper-core plugs are cheaper but need more frequent replacement, while platinum plugs are more durable and slightly more expensive, making them cost-effective in the long run. Not replacing spark plugs can lead to delayed ignition, wasting more fuel, and the savings on fuel will be offset. Maintaining a regular checklist keeps the car running efficiently and reduces emissions, protecting the environment.

Spark plugs are the core components of an engine, and neglecting their replacement can lead to major issues. My CS75 requires spark plug updates every 60,000 to 100,000 kilometers, depending on the situation. Excessive wear on spark plugs can cause difficulties in starting the car, a drop in power, or even the danger of stalling, which requires extra attention during long-distance driving. If you notice increased car vibrations or a sudden rise in fuel consumption during daily driving, check the condition of the spark plugs. Always prioritize safety and address issues promptly to avoid malfunctions that could affect driving.

As an experienced driver who frequently drives, I have firsthand experience with changing the spark plugs on my CS75. Last time, I didn't replace the spark plugs in time and drove up to 70,000 kilometers. The car's power noticeably weakened, and when I took it for , the mechanic said the carbon buildup was severe—it almost damaged the ignition coil. Since then, I proactively check every 50,000 kilometers and set reminders in my phone's memo for peace of mind. Everyone should stay vigilant while driving—don't wait until problems arise to fix them, as it only increases repair costs. Choosing OEM parts or reliable brand spark plugs ensures quality. Regular maintenance also keeps the car's overall performance smoother and more comfortable, making it ideal for family road trips.

In the automotive community, I've noticed many car owners discussing spark plug topics. The replacement interval for the CS75's spark plugs depends on the material. Copper-core spark plugs have good thermal conductivity but lack durability and should be replaced every 60,000 kilometers. Platinum spark plugs, on the other hand, offer superior heat resistance and can last 80,000 to 100,000 kilometers, depending on driving habits—frequent hard acceleration can accelerate aging. Regular removal and inspection of spark plugs are necessary to confirm normal gap conditions. Failure to replace them can lead to ignition system imbalance, affecting engine performance. Unusual clicking sounds should prompt immediate attention to potential spark plug issues, ensuring vehicle reliability and extending the lifespan of major components, saving money and providing peace of mind.
